PLANETARY GEARBOX Russian patent published in 2019 - IPC F16H3/64 

FIELD: machine building.

SUBSTANCE: invention relates to the planetary gearboxes (PGB). Five-speed PGB with two degrees of freedom contains four single-row planetary mechanisms, friction clutch and four brakes. Gearbox input shaft is connected to the first and second planetary mechanisms sun gears and through to friction clutch to the planetary mechanism epicyclic gear. Second planetary gear epicyclic gear is connected to the first planetary gear carrier and to the third planetary gear sun gear. Second planetary mechanism carrier is connected to the third and fourth planetary mechanisms common carrier and to the gearbox output shaft. Third planetary mechanism epicyclic gear is associated with the fourth planetary mechanism epicyclic gear. On the first, second, third, fourth planetary mechanisms epicyclic gears and on the fourth planetary mechanism sun gear, the brakes are installed.

EFFECT: enabling the gearbox design simplification.
